Description
The Crocks Pack Moli INR 21700 P42A 14.8V 8400mAh 4S2P 80A/100A Discharge Li-ion Drone Battery Pack
is a high-performance lithium-ion battery pack designed for drones, UAVs, and RC systems that demand both high voltage and substantial current capacity. This pack is constructed using eight premium Molicel INR‑21700 P42A cells
Each P42A cell has a typical capacity of 4,200 mAh and is rated for a continuous discharge current of up to 45 A per the datasheet. To ensure safe and reliable operation, this pack is rated for 80 A continuous output, with the ability to handle peak bursts up to 100 A,
The P42A cells feature very low internal resistance (~10 mΩ AC), which minimizes voltage drop even under heavy load. With their nominal voltage of 3.6 V, they support a full pack
The battery pack includes a 4‑cell balance connector for safe, balanced charging, allowing you to maintain each series string at equal voltage. A robust discharge lead supports the high-current demands during flight.
This 14.8 V pack is ideal for drones where extra voltage improves motor performance, or for builds where you want to maximize both capacity and discharge capacity without going to very high series counts.
